Referring to fig. 1 to 3, an embodiment of a rear armrest structure 100 is provided, which includes an armrest tube 110 and an elastic armrest 120 sleeved on an outer surface of the armrest tube 110, wherein the armrest tube 110 is fixedly connected with a vehicle body, and the elastic armrest 120 is in interference fit with the armrest tube 110 to achieve a clamping connection.

The rear handrail structure 100 utilizes the elastic characteristic of the elastic handrail 120 to deform and expand the opening of the elastic handrail 120 to be sleeved on the handrail tube 110, and generates a tightening force to the handrail tube 110 when the elastic handrail 120 is restored, so that the rear handrail structure is clamped on the handrail tube 110, and no other connecting piece is required or a connecting structure is arranged on the elastic handrail 120 and the handrail tube 110, so that the elastic handrail 120 cannot fall off after being clamped. During installation, the opening of the elastic handrail 120 is aligned with the handrail tube 110, then the elastic handrail 120 is pressed to fix the elastic handrail on the handrail tube 110, and during disassembly, the elastic handrail 120 is separated from the handrail tube 110 only by being broken off, so that the assembly is simple and quick, the installation cost is low, the handrail function is met, and the aim of controlling the cost is fulfilled.

Alternatively, in one possible implementation of the embodiment of the present utility model, the material of the elastic handrail 120 is plastic.

The handrail made of plastic has elasticity, and the cost of plastic is lower, and the cost of the back handrail structure 100 can be greatly reduced by matching with the installation mode of clamping. In addition, the plastic has low thermal conductivity, and can meet the functional requirements of the elastic handrail 120 for cold prevention in winter and scalding prevention in summer. Illustratively, the elastic handrail 120 is made of PP (i.e. polypropylene), which has light weight and good toughness, and is beneficial to assembly of the elastic handrail 120 and lightweight design of products.

Alternatively, in one possible implementation of the embodiment of the present utility model, the elastic handrail 120 is an integrally formed structure. The elastic handrail 120 with the integrally formed structure can complete the forming process of the whole part in one die at one time, has low processing cost and high quality, and can better realize interference fit with the handrail tube 110.

Optionally, in an implementation manner of the embodiment of the present utility model, the armrest pipe 110 includes a hand portion 111 and connection portions 112 disposed at two ends of the hand portion 111, the hand portion 111 is fixed on the vehicle body through the connection portions 112, the elastic armrest 120 is clamped on the hand portion 111, and an extension direction of the elastic armrest 120 is the same as an extension direction of the hand portion 111.

The hand portion 111 is used for clamping and fixing the elastic armrest 120, and two ends of the hand portion 111 in the extending direction are respectively connected with the two connecting portions 112 and are fixed on the vehicle body through the connecting portions 112. The extending direction of the elastic handrail 120 is the same as that of the hand portion 111, so as to increase the interference fit area between the two, so that the elastic handrail 120 is more stable to mount and is not easy to fall off. The connecting portions 112 at both ends of the armrest 111 may be connected to the vehicle body at the same time to improve the stability of the elastic armrest 120, or only one of them may be connected to the vehicle body to fix the armrest 111.

Preferably, the elastic armrest 120 includes two, the armrest tube 110 includes three connection portions 112 and two armrest portions 111, wherein two ends of one connection portion 112 are respectively connected with ends of the two armrest portions 111, and two ends of the other two connection portions 112 are respectively connected with the other ends of the armrest portions 111 and the vehicle body. The handrail tube 110 is provided around the rear seat passenger, which can protect the passenger, and at the same time, other structures can be provided on the connection portion 112 for connecting the two handrail portions 111, so as to improve the practicality of the handrail tube 110. More preferably, the armrest tube 110 is integrally symmetrical to better fit the vehicle body, so that the occupant is more comfortable in use and the appearance is more attractive.

Alternatively, in one possible implementation of the embodiment of the present utility model, the outer contour of the handrail section 1111 of the handrail portion 111 perpendicular to the extending direction thereof is circular, and the inner contour of the handrail section 121 of the elastic handrail 120 perpendicular to the extending direction thereof is circular arc.

The outer contour of the armrest section 1111 is rounded so that the outer surface of the armrest 111 is smooth, without corners, without impeding the sliding of the resilient armrest 120 along its outer surface and completing the installation and removal process by deformation and recovery. The inner contour of the handrail section 121 is circular arc shape, so that the elastic handrail 120 is provided with an opening for assembly, moreover, the circular arc shape is matched with the circular shape, the interference fit between the elastic handrail 120 and the hand portion 111 can be realized by controlling the radius of the circular arc shape and the circular arc shape, the contact area between the elastic handrail 120 and the hand portion 111 after assembly is large, and the elastic handrail 120 is stable to install and is not easy to fall off. It will be appreciated that in order to achieve an interference fit between the resilient handrail 120 and the handrail tube 110, the radius of the inner profile of the handrail section 121 should be slightly smaller than the radius of the outer profile of the handrail section 1111.

Preferably, the inner contour of the hand section 1111 is also rounded to reduce the weight of the handrail tube 110 while facilitating processing; the connecting portion 112 has the same shape and size as the hand portion 111 in the outer and inner profiles of the connecting section perpendicular to the extending direction thereof, so that the outer and inner surfaces of the handrail tube 110 are smooth, and the processing difficulty and cost are reduced.

Preferably, the outer contour of the cross section 121 of the handrail is U-shaped, three sequentially connected sides are planes, arc surface transition is arranged between two adjacent planes, and the shape can better support the hands of the passengers and improve the user experience.

Optionally, in one possible manner of the embodiment of the present utility model, the inner contour of the handrail section 121 covers more than half of the outer contour of the handrail section 1111, that is, more than half of the outer surface of the handrail portion 111 is wrapped by the elastic handrail 120, so that the elastic handrail 120 is wrapped on the outer surface of the handrail tube 110 in a folded posture, and is not easy to fall off when being impacted accidentally, thereby further improving the installation firmness of the elastic handrail 120.

It will be appreciated that if the wrapping area of the elastic handrail 120 is too large, the elastic requirement of the elastic handrail 120 will be high, and plastic deformation of the elastic handrail 120 will easily occur during the assembly process. Thus, it is preferred that the inner contour of the handrail section 121 covers three-fifths to four-fifths of the outer contour of the handrail section 1111, e.g. the inner contour of the handrail section 121 covers three-quarters of the outer contour of the handrail section 1111.

Alternatively, in one implementation manner of the embodiment of the present utility model, the elastic handrail 120 is provided with a protrusion 123 at least partially covering the edge of the elastic handrail 120, and the width of the protrusion 123 is greater than the thickness of the elastic handrail 120.

The protrusion 123 is provided at an edge of the elastic handrail 120, covering a part or all of the edge. The width of the protrusions 123 is greater than the thickness of the elastic handrail 120 to protrude from the outer surface of the elastic handrail 120. It will be appreciated that in order to avoid affecting the interference fit between the resilient handrail 120 and the handrail tube 110, the protrusions 123 should not protrude from the inner surface of the resilient handrail 120. The thickness of the elastic handrail 120 is generally thinner, and the elastic handrail 120 is not convenient to detach after being clamped on the handrail tube 110, and the protrusions 123 enable the elastic handrail 120 to have a thickening effect at the edge, so that the elastic handrail 120 is easy to be broken by applying force at the protrusions 123 during detachment.

Optionally, in an implementation manner of the embodiment of the present utility model, an anti-slip structure is disposed on an outer surface of the elastic handrail 120, and the anti-slip structure is used to increase friction between the elastic handrail 120 and a passenger's hand, so as to prevent the passenger's hand from sliding down and improve safety.

In the present embodiment, the anti-slip structure is not limited as long as it can increase the surface roughness of the elastic handrail 120 and increase the friction between the elastic handrail 120 and the hands of the passenger.

Optionally, in an implementation manner of the embodiment of the present utility model, the anti-slip structure includes a plurality of linear lines 122 disposed on an outer surface of the elastic handrail 120 in parallel, and an extending direction of the linear lines 122 is the same as an extending direction of the elastic handrail 120.

The provision of the linear lines 122 makes the outer surface of the elastic handrail 120 take on an uneven state, thereby increasing the friction between the elastic handrail 120 and the hands of the passengers. Preferably, the anti-slip structure covers the entire outer surface of the elastic handrail 120 to improve anti-slip effect and reduce restriction of the placement position of the passenger's hands.

The present embodiment also provides a motor vehicle including a vehicle body and the rear armrest structure 100 as set forth in any one of the above provided on the vehicle body.

The motor vehicle can be an electric vehicle, a motorcycle and the like. The motor vehicle includes the same structure and benefits as the rear armrest structure 100 of the previous embodiments. The structure and the advantages of the rear armrest structure 100 have been described in detail in the foregoing embodiments, and are not described herein.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
